Objective: To investigate the correlation between gastric acid pH value of patients with acid-related gastric diseases and the score of their life events. Methods: To evaluate the LES (life event scale) of the 108 patients with acid-related diseases were divided into 3 groups according their cluster of gastric acid pH value, group one pH 1.3 (n=37), group two pH 1.6~1.7(n=32), group three pH 2.1~4.5(n=39). Results: The LES total score and factor scores increased with the gastric acid level, the total score of the three groups were 40.0?20.6, 15.1?9.2, 6.4?6.5 respectively, the differences among the three groups were significant (F=43.26,P

ObjectiveThe psychologic health level of college and secondaryschool students and the relevant fac- tors were investigated to scientific basis and guidance for school mental health work. MethodsStandard 1251 cases were drawn from 1% of students in colleges and middle schools of Shaanxi province. Taking 14 psychic health level indexes in SCL-90 as dependent variable and 109 indexes of psychic health back ground as in-dependent variable, multi-factor analyses have been made. Results22.6 % of students had relatively serious psychological problems. The score of SCL-90 in females was a little bit higher than that in males. The scores of students at both universities and se- nior middle schools were higher than that in junior middle schools students. The score of SCL-90 of students who came from the countryside was higher than that of city students. The score of the whole students was higher than that of the normal. The students with psychic problems showed obsession, interpersonal sensitivity, depression, anxiety, paranoia and hostility. Factor-analysis showed that influencing factors included history of positive individual risking behavior, physical conditions,grade,address, family influences, menses and sexual prombles, bad relation with others, poor self-assessment. ConclusionThe psychologic health level of the students investigated is lower than that of the whole society. The factors, which hamper psychic health of students, are biological ,psychological and social in nature.
